ATTORNEY United States Patent Office 3,149,380 Patented Sept. 22, 19643,149,380 SLIDABLE AND SWINGABLE WINDOW SASH CONSTRUCTION Lionel J.Richard, 337 Locust Ave., Port Chester, N.Y. Filed June 26, 1961, Ser.No. 119,372 4 Claims. (CI. 20-49) The present invention relates to awindow assembly in which both the upper and lower window sashes may beswung or pivoted out of the window frame into the room for cleaningpurposes.

An object of the present invention is to provide a window assembly fornew constructions or for replacement of existing window units wherebythe cleaning of outside portions of the windows is facilitated.

Another object of the present invention is the provision of a simplifiedswingable window sash that is simple to operate and is relativelyinexpensive to manufacture.

A further object of the present invention is to provide slidableelements in a groove insert in the window frame, the slidable elementsbeing releasably attached to the window sashes by a latchingarrangement.

A further object of the present invention is to provide a uniquelatching arrangement for easily and rapidly releasing the window sashesfor swingable or pivotal movement.

Another object of the present invention is the provision of a windowassembly construction which is reliably effective for the purposesintended.

The above and other features, objects and advantages of the presentinvention will be fully understood from the following descriptionconsidered in connection with the accompanying illustrative drawings.

FIG. 1 is a partial sectional view of the slidable and swingable windowsash construction embodying the principles of the present invention.

FIG. 2 is a perspective view of the overall window assembly in which thewindow sashes have been swung to their inward positions, and the uppersash rests on the lower sash.

FIG. 3 is a front elevational view of a latching device for the windowsash and FIG. 4 is a sectional view of an alternative latching devicefor the window sash.

Referring more particularly to the drawing and especially to FIGS. 1 and2, in which the window unit is indicated generally by the numeral and isconstituted of a frame 12 having upper sash 14 and lower sash 16slidable therein as well as swingable into the interior of the room asillustrated in FIG. 2. A pair of slides or arms are each secured at oneend 20 to the lower sash 16 while the other end 22 is provided with aslider 36 which is slidable in one of the slidable elements in thegrooves or recesses in the window frame 12 hereinafter more fullydescribed. The bottoms of lower sash 16 and upper sash 14 are providedwith lateral swivel pins 24 which are also slidable in theaforementioned grooves.

In FIG. 1 a groove insert 26 is installed in the frame 12 between woodstop 28 and blind stop 30. It should be noted that the identicalelements shown in FIG. 1 on one side of frame 12 also appear on theother side of the frame 12, but are omitted in the illustrations forpurposes of clarity. Slidable in section 26a of the groove insert 26 isan element 32 having a hook-shaped end portion 34 enclosing a portion ofthe slide 18 with slider 36 secured thereto. The balances for both theupper and lower sashes are illustrated in dashed lines in FIG. 1 andbear the reference numerals B. These sash balances are of thewell-known, conventional type. Lower sash 16 is provided with anL-shaped cover member 38 enclosing the slide 18 and slider 36. Slidablein section 26b of the groove insert 26 is another element 40 for theupper sash 14. Element 40 also has a hook-shaped end portion 42 enclosedby L-shaped cover member 44 secured to upper sash 14. As shown in FIG.1, there are means shown for connecting the balances B to slidableelements 32 and 40.

FIG. 3 illustrates one of the latching devices which may be utilized forboth the upper sash 14 and the lower sash 16. This latching device maybe located on both the top corners of the sashes although only one isshown for illustration purposes. The latching device referred togenerally by the numeral 46 is a relative flat plate pivoted at 48 toone of the slidable elements 32 and 40 and is movable from a latchedcondition shown in full lines to the unlatched condition shown in dashedlines. In the unlatched condition of latching device, the slot 50 isremoved from engagement with screw 52 by means of a finger piece 51 andpoint 54 is seated in groove 56 of the window frame 12. The latchingdevice 46, in the dashed lines position, prevents the lower sash 16 fromsliding upwards in the frame 12 due to force exerted by the balances Bbecause the point 54 engages the window frame 12 and at the same timepermits the sash to be swung into the interior of the room for cleaningpurposes. In the latched condition of the device, as illustrated in fulllines in FIG. 3, the adjacent slidable element 32 is operativelyconnected to the lower sash 16 thereby permitting the freely slidablemovement of the sash in window frame 12.

An alternative latching device is shown in FIG. 4 coacting with thehook-shaped end portion 34 of element 32. This latching device comprisesa detent 58 having a pivot pin 60 and a spring 62 urging the detent intoengagement with the hook-shaped end portion 34 of element 32. Thus, bymoving the other end 64 of detent 58 laterally to the left against theforce of spring 62 the lower sash 16 becomes unlatched from the frame 12and the sash may be freely swung out of its frame and pivoted inwardlyon swivel pins 24. The latching device disclosed in FIG. 4 isparticularly adaptable for use with the lower sash 16.

While I have shown and described the preferred embodiment of myinvention, it will be understood that the latter may be embodiedotherwise than as herein specifically illustrated or described and thatin the illustrated embodiment certain changes in the details ofconstruction and in the arrangement of parts may be made withoutdeparting from the underlying idea or principle of the invention withinthe scope of the appended claims.

What I claim is:

l. A window construction comprising a frame provided with a grooveinsert in opposite inside sides thereof, a balance in each grooveinsert, upper and lower sashes slidable in said frame and having saidbalances operatively connected thereto, means on each of said upper andlower sashes for permitting the latter to be swung into the interior ofthe room including releasable latching means, a pair of arms eachfixedly attached at one end to opposite sides of said lower sash andhaving a slider at the other end thereof, a slidable element in each ofsaid groove inserts operatively connected to said upper and lower sashesrespectively, and one of said slidable elements comprising a dividingwall separating the same into two portions, one of said portionsenclosing said balance and the other portion enclosing said sliderslidably movable therein, and said latching means in the latchedcondition connecting said sashes to the adjacent slidable elements.

2. A window construction as set forth in claim 1 wherein said latchingmeans is a fiat plate pivoted on one of said slidable elements, saidplate having a slot therein,

ther comprising an L-shaped cover member secured to one of said sashesand enclosing said arm and slider when said sash is located in saidframe.
